Pedestrians perceive differently from the sideway views or the exteriors of the buildings on the way to their destinations. Therefore, the navigation experience can become much different when the path was chosen based on the individual's preference from it is not. By focusing on the effects of the individual pedestrian' path choice on their navigation, this paper presents an algorithm designed for pedestrians to be able to explore their preferred path and proposes a prototype of navigation system based on the algorithm. The navigation support system searches for the best path upon their individual preferences and information of the destination. The system provides the process of retrieving the final path via the pedestrian-support system interaction. The path retrieval is peformed with the combinational matrix of keywords that are formulates Fuzzy theory from the correlations between the terms describing preferences used in the path preference survey. This paper presents the potentials of the path finding method tailored to pedestrians' preferences by a simulation of the proposed path retrieval algorithm.

The purpose of this study is to understand the relationship between physical characteristics and general people's perception. In this study, the physical quantities of artificial lighting were measured from the visual point of the pedestrian and general public perception including preference and satisfaction was examined. As a result of this study, the total luminance and mean luminance had different value in each site. However, there were no significant differences in area and number of light source between sites. The effects of these factors are affected by indoor lighting. In the group of respondents, 10s people, male, students, meeting, 1~2 times a month and 18:00~20:00 had higher satisfaction compared to other groups respectively. A total luminance and mean luminance gave effect on the satisfaction of physical quantities of artificial lighting and the satisfaction on night landscape. With increase in total luminance and mean luminance, the satisfaction was lowered. It is necessary to reflect these factors on the future policies of nightscape.

Physical activity of the people has decreased due to a sedentary lifestyle according to developing the economy throughout the world. It is thought to increase the risk of chronic diseases, including obesity, diabetes, etc. People are interested in walking, which is an easy activity to engage in as an antidote to chronic diseases. The aim of this study is to increase the diminishing physical activity of modem society by inducing walking as part of everyday life through building a walking-based activity-friendly city where people can live merrily, safely and pleasantly. For this purpose, this study conducted a satisfaction survey to dwellers of Jinhae on the physical pedestrian environments which affect determining walking participation and intentions of people, and also provided a valid model to evaluate the effects of the physical environmental factors on walking satisfaction using factor analysis and multiple linear regression analysis. The results are summarized as follows. The 18 variables of the physical pedestrian environments were selected based on pre-literature reviews. The results of the satisfaction surveys showed that the satisfaction of crossing aids in segments was highest, while the building feature was the lowest. Factor analysis was run through a two-step process. The first analysis was conducted to examine the adequacy of this factor analysis on the selected 18 variables. As a result, two variables were removed and the remaining 16 variables were extracted to the four factors by second analysis. Each factor was named function of path, effect of traffic, amenity and safety based on the each factor's commonality. Each factor score of the extracted four factors was set as the independent variable, while the overall walking satisfaction was set as the dependent variable. Then, the multiple linear regression analysis was conducted and showed that all four factors had a positive influence on the overall satisfaction of walking, especially the 'function of path' and 'amenity' factors, followed by 'effect of traffic' and 'safety'. The results of this research will be used as foundational data for creating a walking-based activity-friendly city.

The purpose of this study is to investigate the applicability of the CIE standard on lighting environments to Korea. In the field study, horizontal and the vertical illuminance was measured at the pedestrian road in the central business district of a city, and the questionnaires were conducted to get information regarding pedestrian's satisfaction with lighting environment. Four areas were selected for this survey. That areas have different type of pedestrian roads concerning the lighting conditions and the number of walkers. From the results of the measurements, It is known that the illuminance of pedestrian roads is different according to the lighting conditions and the number of poot passengers. Also the results of questionnaires show that the illuminance of the pedestrian roads affect to the pedestrian's satisfaction. Lastly, the CIE standard on lighting environments is applicable to the central business district of the cities in Korea.

The main objective of study was to analyze the effectiveness of transit mall. To this end, this study compared operational status of transit malls in operation (Daegu, Seoul and Busan). For the city of Busan where the latest transit mall became operational in 2015, a discriminant model was proposed to determine user satisfaction/dissatisfaction. The outcomes of comparative study showed that each city has different operational focus - Seoul has focus on traffic demand management, Busan has focus on walking environment, and Daegu has focus on accessibility to public transportation. Also, the discriminant model indicated that market sentiment, convenience of bus service, traffic accident risk, number of pedestrian, market user number have effects on user satisfaction. These results implied that, to improve user satisfaction, measures for market revitalization such as opening events and forming consultative groups need to be prepared and traffic conditions should also be improved through expansion of curfew time, linkage with subway station.

야간 조명은 건강과 복지에 대한 인간의 욕구를 야간시간의 활용을 통하여 충족시킬 수 있도록 도와주고 있다. 또한 조명은 경관의 활성화와 미적 공간 창출의 유용한 도구로 이용되고 있어 근린공원에서의 조명은 주간과 다른 분위기를 제공하여 이용자들의 만족도를 높여주고 있다. 하지만 위험 요인을 가지고 있는 공원에서는 심미적 효과뿐만 아니라 이용자들의 보행 안전을 위한 야간 조명설계의 중요성이 강조된다. 본 연구는 야간 근린공원 이용자들의 보행 안전을 고려한 조명설계를 위하여 시뮬레이션 접근법을 이용하여 대안 조명품질을 비교한다. 기존에 설치된 조명기구와 타 조명기구를 시뮬레이션으로 비교함으로써 조명설계시 시뮬레이션 접근법의 유용성을 제안한다.

The importance of bumper system lies not only in the styling of vehicles, but also in the protection of vehicles and pedestrians from reasonable impact. In this study, we proceed to search a method for efficient bumper system without using the impact test and the computer simulation to analyze the bumper system. In the process of the research, we proposed the each method that is used to search the shape that satisfy each regulations in first, because bumper's dimensions to satisfy 'vehicle protection' regulations and form's dimensions to satisfy ‘pedestrian protection' regulations are difficult to exist together. After that we proposed the calculate method and design algorithm that is used to search a reasonable point satisfying the two regulations together.

This research analyzes the residents' satisfaction for the pedestrian space of multi-family housing based on quality index. For this purpose, nine apartment complexes which were built after 2000, are selected and examined by user characteristics of composition factors of pedestrian space. This research also compares residents' satisfaction by evaluation factors of walking environment. The resident survey reveals that the composit type of apartment gives the highest satisfaction to residents followed by a courtyard type, and a straight type the last. In particular, residents show high satisfaction to pedestrian-only space in the case of the composit type of apartment building. The most important factor of walking environment on residential satisfaction is the separation of car and pedestrian path of main entrance. Above all, suitability of construction laws and regulations should be reviewed for safer and more amenable walking environment.
